111Iverson bracket — In mathematics, the Iverson bracket is a convenient notation that denotes a number that is 1 if the condition in square brackets is satisfied, and 0 otherwise. More exactly,: [P] = egin{cases} 1; mbox{if } P mbox{ is true;} 0; mbox{otherwise.}… …
112Spectral asymmetry — In mathematics and physics, the spectral asymmetry is the asymmetry in the distribution of the spectrum of eigenvalues of an operator. In mathematics, the spectral asymmetry arises in the study of elliptic operators on compact manifolds, and is… …
113Tanaka's formula — In the stochastic calculus, Tanaka s formula states that:|B t| = int 0^t sgn(B s) dB s + L twhere B t is the standard Brownian motion, sgn denotes the sign function:sgn (x) = egin{cases} +1, x geq 0; 1, x < 0. end{cases}and L t is its local time …
114Tanaka equation — In mathematics, Tanaka s equation is an example of a stochastic differential equation which admits a weak solution but has no strong solution. It is named after the Japanese mathematician Tanaka Hiroshi.Tanaka s equation is the one dimensional… …
115Superellipsoid — In mathematics, a super ellipsoid or superellipsoid is solid whose horizontal sections are super ellipses (Lamé curves) with the same exponent r , and whose vertical sections through the center are super ellipses with the same exponent t .Super… …

118Superquadrics — In mathematics, the superquadrics or super quadrics are a family of geometric shapes defined by formulas that resemble those of elipsoids and other quadrics, except that the squaring operations are replaced by arbitrary powers. They can be seen… …
119Square root of a matrix — In mathematics, the square root of a matrix extends the notion of square root from numbers to matrices. A matrix B is said to be a square root of A if the matrix product B · B is equal to A.[1] Contents 1 Properties 2 Computation methods …
